Dijkstra's algorithm, conceived by Dutch computer scientist Edsger Dijkstra is a graph search algorithm that solves the single-source shortest path problem for a connected graph with nonnegative edge path costs, producing a shortest path tree.
Can somebody tell me why Dijkstra's algorithm for single source shortest path assumes that the edges must be non-negative. I …
